Lu Zong took the cloth away from his nose, wrung the urine out of it, sniffed it, and Mu Xiong hurriedly asked, "Well, is it pure?" Meanwhile, the Fatty couldn't stop laughing beside them, finally gasping out between chuckles, "This old brother must have prostate issues. I clearly saw your stream split in two just now, hah! That killed me. Hahaha…." Ma Xiong glared at the Fatty with murderous eyes until the Fatty realized his lapse in manners, his face instantly flushing crimson as he fell silent.

He withdrew his deadly gaze, surveyed their surroundings, and his eyes settled on a corner of the cave. Seeing Ma Xiong's strange expression, Lu Zong followed his line of sight. There, in a quiet recess of the cave, lay a rusty sign. The few of them rushed forward, eager to see what the sign said.

Lu Zong picked up the sign and wiped the dust off it, then polished it against a stone, rubbing away the heavy rust until the writing became somewhat discernible. Ma Xiong recited, speaking his rough Mandarin, "Imperial Japanese Army, Seventh Battalion, Biological Weapons Research Group." Location: Shenhe District, Liaoning Province… The rest was obscured by years of corrosion, but seeing this much had already paralyzed them with fear. Lu Zong stammered, "Liaoning Province, Shenhe…? How is that possible?

Liaoning Province? Xinjiang Province? How could it be? The distance is immense; how could it possibly appear here?" At the same time, Ma Xiong and the Fatty were stunned, completely baffled.

Lu Zong mumbled, Did we time-travel? A time machine? No, it must be a hallucination? Saying this, he frantically looked down at his hand.

The sign bearing the name of Liaoning Province still lay there, so clear, so real. He felt his hands trembling. He cautiously glanced at the other two men, who were equally frozen in shock, unsure what to do. It was the Fatty who finally broke the tension.

"Forget it, let's just keep moving. We shouldn't stay here. This place is the junction between a tomb and a laboratory, surely a place of temporal instability. Who knows what dangers await us.

We should leave as quickly as possible." The three made up their minds and tossed the sign aside, yet the question of what had happened continued to churn in their minds. Had they really encountered a time tunnel? Had the people here mastered this tunnel long ago, and they were merely pawns set up by the shamans, every move controlled? The thought sent Lu Zong’s head into a chaotic spin.

They didn't even know who their enemy was now. Based on the current situation, their clearest adversary was that Loulan beauty. Had that mummy traveled to the modern era through the time tunnel, seeking ferocious revenge on those who violated her remains? Were the shamans here the invincible army controlled by the female corpse's soul?

Or was this merely some sacrificial ritual, and they were trapped here as burial objects, left to perish by the sorcerers? Everything spun in his mind like an unsolved mystery, giving him a headache. Better not to think about it. The Fatty, walking in front, suddenly turned back and assessed the situation.

Lu Zong knew that in places like this, tomb robbers were always more seasoned than he was. No matter how skilled he might be, it was all just theory until a real fight broke out; practical experience forged through life-and-death struggles was what mattered. Therefore, Lu Zong felt he had to follow the Fatty’s lead right now. The Fatty made a rough estimation, then turned to the other two.

"We are currently on the fringe of the biological weapons research lab, and simultaneously, at the very entrance of the tomb passage. If we keep moving forward, we'll enter the tomb. If we retreat, we'll end up in the Hall of Yama. Our only option now is to go forward.

I came from that direction, and I know the way back. Let's just hope this tomb isn't massive; getting lost would be a real problem." Ma Xiong declared without hesitation, "Alright, let's enter this passage and push forward. I don't want to report to Yama so young." With that, he took a few steps forward, preparing to enter the tomb. But Lu Zong stepped forward and stopped Ma Xiong.

"Wait, we can't go in yet. We still have a companion in here. Have you forgotten Ganda?" Ma Xiong turned back, finally realizing Ganda hadn't been found. He scratched his head in annoyance and frowned.

The Fatty asked, looking utterly confused, "What? Do you two have acquaintances lost inside? That's careless of you. How could you lose someone?" Lu Zong said, "Brother, we won't trouble you further.

If you feel we are a burden, you should go ahead. We are determined to find our companion before we leave." This statement was immediately met with opposition from Ma Xiong. "How can you say that? We live together, we die together.

Even if we have to fight you to the death today, we won't let you abandon us here. That’s what loyalty means, don't you understand? But Lu Zong, I still have to advise you—think clearly. Ganda, he's a man..." Lu Zong’s expression barely changed upon hearing this; he just sighed.

"If my guess is right, Ganda is with Han Chong and Lusha right now. They went missing together. That means Han Chong and Lusha must also be trapped in the lab. So, we have to rescue all of them, or we won't leave this cursed place even if it kills us." With that, he turned and headed toward the ear-shaped opening, intending to squeeze through and search for the others.

However, once inside, he could not find the opening anywhere. Puzzled, he called Ma Xiong over to help search for the time tunnel. But now, the mountain walls were smooth, hard, continuous stone—not a trace of a break or hole remained. This astonished both of them.

Ma Xiong stammered, "What is going on? There was clearly a hole here just a moment ago, but why is it gone now?" Lu Zong looked up above him, equally frustrated and utterly perplexed. But the Fatty, standing outside, suddenly exclaimed in surprise, "Why are you two moving?" Lu Zong and Ma Xiong snapped to attention, seeming to grasp something, and hastily looked toward the Fatty’s position. Indeed, they saw the Fatty slowly rotating.

Could it be that the stone chamber they were in was rotating on its own? They could clearly feel the stone chamber slowly turning because they watched the Fatty gradually shift his position, moving from the center to one side of the room. Since the Fatty was standing outside the stone chamber, he wasn't rotating with it; he could easily observe the rotation of the two inside. This explained most of what they couldn't understand.

Lu Zong speculated that the chamber was indeed turning, and the direction of rotation might even vary in different sections. Take the female corpse's coffin, for example; perhaps the section it rested on was spinning counter-clockwise, while their section spun clockwise. This would cause the coffin to drift away from them, making it look, to an observer, as if the coffin itself had moved. This deduction was immediately met with approval from Ma Xiong.

"Good, well said! Exactly what I was thinking." Lu Zong continued, "And the beginning part—why couldn't we see each other when we were in the same room? That makes sense here too. Imagine you are in this section, and I am in the room next to you.

Although we are in different rooms, the various panels of the rooms are all rotating, and at different speeds and in different directions. This could easily cause sections of the room to rotate differently, swapping material from another room over to ours. A segment of this room's panel might have exchanged places with a segment from another room. I suspect we were originally in two entirely separate stone chambers, but due to this temporal anomaly, you ended up in my space, allowing us to meet, while you felt no movement at all." "That doesn't seem right," Ma Xiong countered.

"If what you say is true, we arrived here by shifting through different panels. But look, these rooms are separated by massive stone blocks. Even if the floor panels could move up from below, what about the people on those panels? How could they move across without being crushed by the walls?" Lu Zong paused, speaking without full certainty.

"In my opinion, there must be hidden doors in these walls. When the panel exchange happens, they open to allow objects on the shifting panels to pass through the walls safely. Let's look around. If I’m not mistaken, there should be at least three stone chambers here.

You, me, and Ganda are probably separated into different ones. If we can find the panel that initiates the shift and open the corresponding door, we can search room by room. We should be able to find Ganda. Furthermore, we deduced earlier that Ganda must also be trapped in a coffin like us, which reduces the amount of labor.

I believe we can rescue Ganda soon. As for the Fatty, he just needs to wait here and keep reminding us what the true exit is so we don't get lost." With the plan laid out, Lu Zong and Ma Xiong set off in search of Ganda. They measured the length of the chamber and placed a stone marker every three meters, laying down about a dozen markers. Finally, they stood quietly to observe the changes in the direction of these stones.

They discovered that the rotation of any two adjacent stones was the same, indicating that a distinct section or panel was demarcated every six meters. Each block rotated in a different direction and at a different speed. If they labeled the sections from the inside out as one, two, three, and four, then one and three turned clockwise, while two and four turned counter-clockwise. "Let's check near the stone walls within each section to see if we can find a hidden door." With that, the two moved towards the stone walls, slowly examining the rock faces along the four rotating sections.

This task proved far more demanding than Lu Zong had imagined. A panel shift occurred only every six meters, and while six meters doesn't sound far, remaining stationary for long on a rotating panel was no easy feat. Since they had reached the wall and the door hadn't opened automatically, it implied that door openings followed a specific temporal pattern; they couldn't force them. Moreover, the duration the wall stayed open must be extremely brief.

They would have to rush into the adjacent room during that window, or risk being instantly crushed by the shifting stone masses.
